CoolWebSearch: The Malware That Took Over Your Browser

CoolWebSearch didn’t lock your files. It didn’t steal your data. But it took over your browser and made surfing the web a nightmare. One moment you’re trying to check the news, next thing you know, you're stuck on a sketchy website full of junk ads.

What Was CoolWebSearch?

CoolWebSearch was a sneaky piece of software called a browser hijacker. It didn’t ask for permission. It just barged in, changed your homepage, messed with your search engine, and sent you to websites you didn’t ask for.

You’d try to visit Google, but CoolWebSearch would throw you somewhere else. It was annoying, confusing, and hard to get rid of.

Even worse? It didn’t stop at one change. You’d fix your settings… and it would just change them back again.

How Did It Spread?

This thing popped up in the early 2000s, when people were downloading free games, toolbars, and other programs from random websites.

CoolWebSearch often came bundled with other software. You’d think you were installing something harmless, but secretly, this hijacker came along for the ride. It also spread through fake updates or pop-up ads pretending to be warnings.

Once it was on your system, it didn’t play nice. It could install other adware too, making your computer even slower and your browser messier.

Who Did It Target?

CoolWebSearch didn’t go after big businesses or government systems. It went after regular people at home.

If you used a Windows computer and didn’t have strong antivirus protection, you were a prime target. People didn’t realize their browsers had been hijacked. They just noticed something felt off, weird homepages, crazy search results, or constant redirections to shady sites.

Why It Was a Big Deal

CoolWebSearch was a wake-up call. It showed that malware didn’t have to be flashy or destructive to be a huge problem.

This thing didn’t steal passwords or money. It just annoyed people into giving up. It made browsing the web feel impossible. And that kind of disruption was a big deal, especially back then when people didn’t know how to fight back.

It also proved that even a simple browser hijacker could earn money, by forcing users to visit ad-filled pages over and over again.

Ask Toolbar: The “Helpful” Add-On That Took Over Your Browser

The Ask Toolbar seemed harmless. It promised easier web searches and handy tools. But once it got into your browser, it changed your homepage, hijacked your search engine, and made it tough to get rid of. It wasn’t a virus, but it definitely wasn’t welcome.

What Was Ask Toolbar?

Ask Toolbar was a browser extension, one of those toolbars that sits right under your address bar.

It usually came bundled with free software, especially Java updates or download managers. You’d install one thing, and suddenly Ask Toolbar was sitting in your browser too.

It didn’t ask much. Sometimes it didn’t even make itself obvious. But once it was there, it changed your search engine to Ask.com, set your homepage to their site, and made itself hard to remove.

How Did It Spread?

Ask Toolbar spread by riding along with free programs.

Most people didn’t realize they installed it. The option to say no was often buried in tiny checkboxes or skipped entirely if you clicked “Next” too fast. This trick, called bundled installation, made it super common in the mid-2000s to early 2010s.

You didn’t need to click anything shady. You just wanted to update Java… and boom, Ask was on your browser.

Who Did It Affect?

Ask targeted everyday computer users. People who weren’t super tech-savvy.

It showed up on school computers, family PCs, and office desktops. Most victims didn’t even notice the change until their homepage or search engine was different. Suddenly, Google was gone, and everything looked off.

And the worst part? Trying to remove it wasn’t easy. Even after uninstalling it, parts of Ask would stick around, changing settings again the next time you opened your browser.

Why It Was a Big Deal

Ask Toolbar didn’t steal your credit card or lock your files. But it taught the world a big lesson: even "legit" software can act shady.

It blurred the line between helpful tools and unwanted junk. It opened the door for a wave of similar toolbars and extensions that took advantage of user trust.

Eventually, antivirus tools and web browsers started flagging Ask Toolbar as a PUP, a Potentially Unwanted Program. That’s not quite malware… but it’s definitely something you don’t want.

Babylon Toolbar: The Pushy Add-On That Hijacked Your Browser

The Babylon Toolbar didn’t knock on the door, it just barged in. You’d install a free app or translator, and suddenly your browser looked different. Your homepage was gone. Your searches got hijacked. And Babylon was behind it all.

What Was Babylon Toolbar?

Babylon Toolbar acted like a browser helper, but it caused way more trouble than help. It usually showed up during the installation of free programs, especially translation tools.

You’d hit "Next" a few times, and boom, Babylon was in. It changed your homepage, took over your search engine, and redirected you to its own search page without clearly asking.

Even worse? It was stubborn. It didn’t want to leave.

How Did It Spread?

Babylon didn’t need to trick you with viruses. It used something sneakier: bundled installs.

It came packaged with software you actually wanted. The download looked legit. But hidden in the setup was a pre-checked box for Babylon. If you didn’t uncheck it, you got the toolbar. Sometimes, even unchecking it wasn’t enough, it installed anyway.

This happened a lot between 2012 and 2014. People everywhere ended up with Babylon without meaning to.

Who Did It Target?

Babylon didn’t care who you were. If you used a computer and downloaded free tools, you were a target.

It mostly affected everyday users, students, families, and anyone just trying to get a free translation app. Suddenly, they’d open their browser and everything felt off. Search results looked weird. The homepage had changed. And removing Babylon? Not easy.

It didn’t just uninstall like a normal app. It stuck around. Even after you deleted it, it could still reset your settings the next time you opened your browser.

Why Did It Matter?

Babylon showed how something that looks helpful could actually be really sneaky.

It wasn’t a virus. It didn’t steal your files. But it took control of your browser without asking, and that’s a big deal. It made people feel like they weren’t in charge of their own computer anymore.

Babylon helped shape the way we deal with software today. Security experts started calling tools like this PUPs, Potentially Unwanted Programs. More antivirus tools started flagging them. And software installers slowly got clearer about what they were adding.

Conduit Search: The Search Engine That Hijacked Your Browser

Conduit Search didn’t look like a threat. It acted like a helpful search tool. But once it got in, it took over your browser. It changed your homepage, redirected your searches, and even tracked your personal data, all without clearly asking.

What Was Conduit Search?

Conduit Search was part of a sneaky bundle called the Conduit Toolbar. On the surface, it looked like just another browser add-on. But once you installed it, it went straight to work changing your settings.

• Your homepage? Gone.

• Your default search engine? Replaced with Conduit Search.

• Your privacy? Tracked for ads and who knows what else.

It didn’t ask nicely. It just took control.

How Did It Spread?

Conduit didn’t need viruses or pop-up traps. It used a simple trick, bundling.

It came packaged with free programs and installers, especially around 2012 to 2015. If you rushed through the install and didn’t uncheck the “extra offers,” you gave Conduit a free ride into your browser.

Even people who tried to say no sometimes still got it. And once it was in, it was hard to remove.

Who Did It Target?

Conduit Search didn’t go after businesses or hackers. It went after regular people, students, families, anyone trying to install a free app.

It targeted those who clicked “Next” too fast. And once it got in, it didn’t just annoy you with a new homepage. It also collected your search history, tracked your clicks, and probably sold your info to advertisers.

That made your browser slower, messier, and way less private.

Why It Was a Big Deal

Conduit didn’t break your computer. It didn’t steal your credit card. But it did something just as sneaky: it acted like it belonged there.

It blurred the line between legit software and shady behavior. And because it was packaged with real programs, lots of people trusted it without knowing what it was doing behind the scenes.

Eventually, security experts had enough. They labeled Conduit as a PUP, Potentially Unwanted Program. That’s the nice way of saying: “You probably didn’t want this on your system.”
